	Title		: NEMO Route Optimisation Problem Statement

The NEMO working group has developed a protocol suite, extending the
   notion of edge-mobility on the Internet to include that of network
   mobility. This implies that a set of nodes, along with their mobile
   router, change their point of attachment and that traffic to these
   nodes is tunneled to be delivered through their new point of
   attachment. This mechanism is transparent to applications in that
   existing traffic to a node is being encapsulated and tunneled,
   regardless of where the network containing the destination node is
   attached.

   The NEMO specification is not limited to a single level of mobile
   networks, attaching to the stationary Internet. Rather, arbitrary
   levels of nested mobile networks are supported, employing for each
   level of nesting the same encapsulation and tunneling mechanisms.

   With arbitrarily deep nested mobile networks, the overhead incurred
   through tunneling and encapsulation of data traffic can, however,
   become large. As a consequence, a number of different proposals
   exist, which aim at performing "route optimization" for nested mobile
   networks.

   This document aims at describing the different scenarios in which
   route-optimization is desired, as well as the different proposed
   solutions for achieving route-optimization in nested mobile networks.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
